assurance wireless paying for unlimited? Internet

I am a customer of assurance wireless and i pay for unlimites calls texts and internet 32.10 mo. I am not able to resolve internet issues with them  since  march . i made  several calls and spend quite a bit of time  with troubleshooter they have not resolved the issue .  i was told sprint was having some issues . today may 22 2013 i called and was told issue resolve and i could get on the interne .

that wasn't true. called back another tech. said  headquarters are upgrading and there was nothing they could do  . well i am upset because they should have told me that from the beginning. deceptive and fraudulent practice    yet and still they took  32.10 .i am going to change providers . frustrated in Nc and they should be made to  refund some of your money
